When referring to magnetic properties, magnet lifters can be categorised into three (3) types: permanent magnet lifter, electromagnet lifter and permanent electromagnet lifter. Let’s have a look at each of these types.

Permanent Magnet Lifter

These magnets are primarily utilised for lifting press moulds, blocks, steel plates, etc. As well as this, they are also used to assist with loading and unloading machinery during operation. Further, they can elevate moving iron blocks and other industrial magnetic materials. Permanent magnet lifters are simple to use and operate, as they are safe to handle therefore being widely used as lifting devices in docks, factories, transportation and warehouse industries. By incorporating these types of heavy-duty magnets into your operations, you can drastically improve your productivity.

Electromagnet Lifter

These types of industrial-strength magnets are also known as electromagnetic lifters or lifting electromagnets as they are known for delivering a significant holding power through an inbuilt specialised, penetrating magnetic force which is capable of lifting thicker items such as bundled rebars, beam blank profiles, multiple sheets, and scrap items.

Permanent Electromagnet Lifter

These heavy-duty magnets have a permanent magnetic field, but when provided with power, the magnetic field is offset. This electromagnet type is utilised when the magnetic force is necessary to run. This type of magnet lifter is highly energy-saving and safer for the handler than the electromagnet lifter, as the former expends no power during the lifting process. Electricity is only utilised in the MAG and DEMAG stages. Further safety benefits include during a sudden power failure, the load being lifted will not fall or detach as the magnetic force remains on.
